DECORATED STOVE-PlPE.

SPECIFICATION forming part of Letters Patent No. 326,094, dated September 15, 1885. Y

' Application inea May 25, 1585. (No model.)

To all whom it may concern:

Beit known that I, ANDREW R. BENNETT, of the city of Utica, in the county of Oneida and State of New York, have invented a new and useful Improvement in Decorated Stove- Pipe, of which the following is a specification.

Heretofore various efforts have been made to decorate the external surface of stove-pipe formed from sheet metal,` all of which efforts have proved unsatisfactory, mainly for the reason that no metallic or other paint has been found which will adhere to a metallic surface sufficiently strong to give satisfaction to those using the pipe. In the majority of cases the paint or decorated surface Hakes and peels off. I overcome this trouble by providing a stovepipe formed of brous materialQ-such as asbestus, or of a substance of' which this is the principal ingredient. By the use of asbestus card-board of suitable thickness and dinien sions a light, durable, and cheap pipe can be produced capable of receiving and retaining suitable metallic paint upon its fibrous surface for decorating the same with designs to suit the manufacturer.

In the accompanying drawings, Figure 1 represents a sheet of fibrous material with the surface decorated ready for use. Fig. 2 represents an illustration of a length of pipe constructed from the decorated sheet illustrated in Fig. l. Fig. 3 represents a side view of a decorated elbow constructed as .hereinafter more fully described.

In the accompanying drawings a single form of decorationV is represented. It is quite obvious that any other form or style of decoration may be used to suit the wishes of the manufacturer.

In constructing stoveepipe of librous material and to decorate the same with metallic paints I proceed substantially as follows z Sheets of asbestus of the required size and thickness are cut to thev required size for use in constructing the pipe. These sheets thus provided are preferably submerged in a bath formed from water and glue to give the board the required stiffness, a solution of glue and lard-oil, or a solution of silicate of soda dissolved in water, or any other similar compounds which willimpart to the sheets a sufficient degree of stiffness and to hold the fibers compactly for forming a smooth and even surface. The sheets of cardboard thus provided should be kept in the bath a suiicierit length of time to secure a complete saturation. They are then taken from the bath and passed between rollers under pressure. These rollers are preferably heated for producing a smooth and even surface. desired, may be pressed ilat to remove any wind that maybe left by passing the same between the rollers. I then provide a woodcut or electrotype lfor printing any desired pattern that may be wished upon the sheets before the same are formed into a pipe. The woodcut or electrotype is put into a printingpress and thesurface inked with ordinary inetallic ink of any desired color. Theimpression is then made with a press upon the surface of the sheets. The sheets after the decoration is printed on them are passed through The sheets thus rolled, if 6o forming-rolls for bending thesheets into proper shape to be constructed into pipe. The elbows are formed by pressing them into shape with a press and dies formed for that purpose.. The

elbows are pressed into shape preferably in` halves. The joints of the pipe and elbow may be riveted, cr the edges'of the pipe and elbow where the lap comes may be saturated with sti ffening material before mentioned, and the seams lapped and passed between rollers under press` ure for securing'a proper seam in the pipe or elbow. Dierent methods may be used to accomplish the same purpose.

What I claim as new, and desire to secure i by Letters Patent, is-- rlhe herein-described process of decorating and constructing stovepip'e formed of fibrous material.
